Description

  The present invention relates to a kind of card reader, and in particular, has a hollow case that conforms to a USB plug type, and an insertion seat on the rear side of the hollow case into which an external electronic card can be inserted vertically. The present invention relates to a card reader that achieves the effective use of space required for connection between a card reader and an electronic device, has wide applicability, good expandability, and meets market demands.

  Modern technological advances have brought constant improvements and advances to many digital products, and are entering the era of serialization. New products such as digital products, digital televisions, digital audio equipment, MP3 players, digital cameras, electronic dictionaries, PDAs, or other electronic products are emerging one after another. In many digital products, data recording, data access, recording data updating, etc. are usually performed by a memory card, and further, data in the memory card is read or stored by a card reader. However, for ease of use and ease of portability, many digital products are designed for light, thin and small directions, so internal components need to be reduced in volume, which makes small memory cards Need to be designed for use in digital products.

  Currently, commercially available memory cards have standards such as MMC (Multi Media Card), Compact Flash (registered trademark) card, SmartMedia (registered trademark) card, Memory Stick (registered trademark) card, SD (registered trademark) card, etc. There are memory cards that are successively smaller in volume and larger in capacity, such as mini SD (registered trademark) and micro SD (registered trademark) cards.

  In addition, the card reader is an interface between the memory card and the computer, and data is transmitted by connecting the card reader to the USB port of the computer, and the card reader is quickly read by the computer in a plug-and-play manner. However, the volume of card readers currently on the market is relatively large, takes up too much space and is too inconvenient to carry due to its large volume, and the overall weight of the card reader also increases. It cannot be inserted into a USB port, and the purpose of transmission is achieved by purchasing a separate USB cable and connecting the card reader and the computer. For this reason, there is a disadvantage that the cost is increased and the number of cables around the computer is increased.

  Furthermore, generally, the opening method of the USB port of the computer is installed so as to correspond to the upper and lower slots of the superposition type connector in the casing of the computer, so that the USB port is arranged adjacent to the upper and lower sides on the casing surface. It is used for insertion of prepared storage equipment (for example, USB disk, card reader, etc.). In general, when such a storage facility is connected to the upper USB port, the lower USB port is obstructed by the volume of the storage facility and another storage facility cannot be inserted. For this reason, there is a drawback that only one type of storage facility can be connected to two USB ports at a time.

  Therefore, how to develop a card reader that solves the above-mentioned drawbacks and inconveniences of the above-mentioned conventional technology, and that has a USB plug and can insert an external memory card, and that is light, thin and small, is researched and developed by those skilled in the art. Direction.
